Pyrophosphate color test - Oe - 10YR 6/3; coarse wood fragments - Oe - 5%.
Oa1--2.5 to 6 inches; very dark gray (5YR 3/1), after exposure to air, and very dark gray (5YR 3/1), crushed, sapric material; weak coarse angular blocky structure; very friable, nonsticky and nonplastic; common very fine roots throughout; 40.0 percent fiber unrubbed; 20.0 percent fiber rubbed; 4.4 Bromcresol green; clear wavy boundary. Pyrophosphate color test - Oa1 - 7.5YR 4/3; coarse wood fragments - Oa1 - 15%.
Oa2-- 6 to 10 inches; very dark gray (5YR 3/1), after exposure to air, and very dark gray (5YR 3/1), crushed, sapric material; weak coarse angular blocky and weak coarse granular structure; friable, nonsticky and nonplastic; common very fine roots throughout; 30.0 percent fiber unrubbed; 5.0 percent fiber rubbed; 4.6 Bromcresol green; clear wavy boundary. Pyrophosphate color test - Oa2 - 10YR 3/3; coarse wood fragments - Oa2 - 5%.
Oa3--10 to 17 inches; very dark gray (5YR 3/1), after exposure to air, and very dark gray (5YR 3/1), crushed, sapric material; massive; very friable, nonsticky and nonplastic; 25.0 percent fiber unrubbed; 5.0 percent fiber rubbed; 4.6 Bromcresol green; clear wavy boundary. Coarse wood fragments - 10%.
Oa4--17 to 25 inches; very dark gray (5YR 3/1), after exposure to air, and very dark gray (5YR 3/1), crushed, sapric material; massive; very friable, nonsticky and nonplastic; 10.0 percent fiber unrubbed; 2.0 percent fiber rubbed; 4.6 Bromcresol green; clear wavy boundary. Pyrophosphate color test - Oa4 - 7.5YR 3/3.
Oa5--25 to 31 inches; very dark gray (5YR 3/1), after exposure to air, and very dark gray (5YR 3/1), crushed, sapric material; common medium and coarse very dark grayish brown (10YR 3/2) mottles; massive; very friable, nonsticky and nonplastic; 30.0 percent fiber unrubbed; 5.0 percent fiber unrubbed; 4.6 Bromcresol green; abrupt wavy boundary. Coarse wood fragments - Oa5 - 5%.
C1--31 to 35 inches; dark gray (5Y 4/1) sand; single grain; loose, nonsticky and nonplastic; 5.2 Chlorophenol red; abrupt smooth boundary.
